both fixedly mounted on long links 12 pim.

oted at their upper ends at 13 to short links 14 which turn on lixed pivots 15 and extend normally slightly tilted upward from the horizontal, as shown. The lower ends of links 12 are pivoted at 16 to links 17 extending at the opposite side from the links 111 and pivoted at 18 so as to support the links 12 for up and down vbratory movement inA a manner so that the clearer blades or combs 10, 1l. will move throughout their range of movement close to the surface of the roll and to some extent follow its curve. The link arms 17 have rigid therewith an operating arm 19 pivotally connected at 20 to a link 21 from a short operating crank 22. The opposite operative edges of the clearer blades 10, 11 are spaced apart so as to leave some little extent of ginmng surface of the roll exposed adjacent and just above the operative edge of the doctor knife 6. The clearer blades 10 and 11 have along their operative edges, as seen in Fig. 4, series of relatively shallow rectangular recesses at intervals, thus leaving each edge formed of short spaced apart rectangular projections 23. The recesses in blade 10 are formed opposite the projections on blade 1l, this relation being preserved throughout the length of the blade edges as the projections and recesses are of substantially the same length. This form has been found to beparticularly effective for engaging and rolling the seeds as the cotton-is stripped therefrom by the cooperative action of the roller and doctor blade since the wide recesses permit even large seeds to enter thereinto, while the shallowness of the recesses prevents the premature passing through of the seeds. The blade 10 also carries on its outer side next its operative edge a series of short obliquely upstanding projections or prongs 24 spaced apart and arranged so that as this blade is lifted in its vibratory movement these projections enter certain recesses of the series 25 formed in the adjacent inwardly extending edge of'a do-wnwardly projected portion 26 of seed grid 27. These projections being intermittingly and rapidly projected up through the recesses 25 assist in keeping these recesses open' and promote the escape of seeds, when the ber has been entirely stripped therefrom. The upper clearer may be provided with like downwardly or upwardly and outwardly extending prongs to engage the cotton and promote the turning over thereof. lThe seed grid 27 which constitutes the bottom 'of the cotton supply hop` per and chute` as later described, slopes slightly down toward the ginning point with a. series of slots 28. Feeding devices shown as pronged members 29 fixed on'a vshaft 30 are mountedto operate in the slots 28, these turning in a direction to advance the vcotton to the gmning roll.` The downwardly turned portion 26 of the grid 27 which is spaced .away from .tlierroll some little distance with its lower' end inturned toward the roll provides a pocket next the exposed surface of the roll which is adapted to receive seeds from which the fiber has been only partly stripped and keepthem from falling away until cleared of fiber, and the constant and rapid projection of the prongs 24 up into this pocket prevents any lodging or packing of material therein. This downwardly and forwardly projected portion 26 of the grid 27 facilitates the feeding of the cotton to the roll by reason of the fact that the top edge of the downward sloping side is close enough to the roll to insure that the cotton shall be engaged by the roll surface, and the lower projecting edge of the grid 27 is just far enough down to cause unstripped seeds to be held until they are again raised and presented at the ginning point by the upward movement of the lower clearer. The curved form of the upper clearer blade 11 likewise contributes to effective feeding action as it reciprocates in a way that lessens the obstruction to the cotton being fed in. This curved form of blade is also desirable in that it is a stronger and more substantial construction.

The cotton is preferably supplied to both rolls 2, 3 from a supply hopper 31 having its roller portion 32 formed as a chute and with the vseed grid 27 constituting the bottom thereof as described. This seed grid bottom 27 slopes oppositely downward from a central point 33 toward each roll and a reciprocating member shown as a bar 34 is mounted to operate back and forth over this central part of the bottom so as to feed the cotton in both directions' and apportion it to the two rolls. This feed bar 34 may conveniently be fixed to upstanding arms 35 rigid with the arm 19 and Swingin therewith about the axis as actuated by t e crank 22. The clearer mechanism for the roll 3 is actuated from an arm 17 rigid withthe arm 19 and' extending out opposite the arm 17 being in all respects similar thereto and -similarly connected to operate the clearer mechanism of the roll 3.

Driving impulse for` all the movable parts is preferably imparted from a single rive mantrathat.taaimwaiive a @mamada .al

[in other relations and that likewise" the specic forms and structural arrangement of parts can be widely varied without departing from the principles of the invention. therefore -do not desire to be limited in any i of these particulars, except as set forth in the appended claims.

Having described my `1nventionwhat I claim as new and desire to secure by Letters Patent is: y

1. In a ginning apparatus, aginning roll, a doctor, and oppositely facing yclearers mounted in nning relation to said doctor, a pivoted lin mounting for said clearers arranged to direct the movement thereofv in a path substantially tangent to the roll at substantially unvarying distances from the lroll periphery throughout the range of the movement, and means for imparting vibratory movement to Said clearer mechanism.

2. In a ginning apparatus7 a ginning roll, a doctor, opposite clearers adapted to be brought alternately into ginning relation with said doctor, and a mounting for said clearers to cause them to move across' the roll at a substantially unvarying distance therefrom, said means consisting in a link to which the clearers are fixed and link arms pivotally connected to said link at its ends connections to fixed pivots.

7. 1n a ginning apparatus, a ginning roll having a doctorcoperative therewith, means lfor supplyin lcotton to ginning position having a see grid extending in a general horizontal directionv up to near the ginning point and there formed with a. downwardly sloping and forwardly inclined edge to form point, and f clearer mechanism mounted or vibration to loosen and prevent clogging of thev cotton in said pocket.

8. In a ginning apparatus, a roll having a doctor cooperative therewith, means for supplying cotton to the ginning point having a seed grid extending in a generally horizontal direction to near the ginning point and there having a downwardly sloping and a forwardly projecting portion forming a pocket adjacent the ginning point, said forwardly projecting o'rtion` having recesses in its edge, and vi ratory clearer mechanism having parts to coperate with the operative edge of the doctor for easing and loosening the cotton .and yotherpart-s cooperative with said recesses for lift ing any partially ginned'material in said pocket and keeping said recesses open.

9. In a ginnlng apparatus, a roll having a doctor` coperative therewith, means for supplying cotton to the ginning point having al seed grid extending in a generally horizontal direction to near the ginning point and there having a downwardly sloping and av forwardly projecting portion forming a pocket adjacent the ginning point, said forwardly ,projecting portion having recesses in its edge, and vibratory mechanism having a vertically extending clearer blade with a recessed edge for coperation with the doctor to ease and loosen the seed from the cotton and upwardly extending diverging prongs thereonadapted to extend into said recesses at the upper limit of movement to keep the same clear and raise any material lodged in said pocket.

10. A ginning apparatus comprising a ginning roll having a doctor coperative therewith, and a clearer mounted for vibral tion adjacent the operative edge of said doctor, said clearer having relatively shallow wide recesses in its operative edge spaced apart to leave like short relatively wide projections between them thus furnishing a relatively large seed engaging edge, said recesses having a greater width than depth a doctor coperative therewith, andspaced apart clearers having oppositely facing op# era'tiveedges mounted in spaced apartrelation for reciprocation adjacent the ginning point, the edge of each of said clearers having relatively shallow wide recesses alternating with relatively short wide projections, with the projections on one clearer opposite the recesses in the other.

In testimonyv whereof, I have signed my name to this specification, in the presence of two subscribing witnesses. v
